ysPoKE--TENoNING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 224,393, dated February 10, 1880,

j Application filed september 16,1879.

To all whom it may concern Be it known that I, TARRENGE CONNOR, of

particularly described with reference to the annexed drawings, and the invention pointed out in the claims. Y

In the drawings, Figure l is a plan view of the machine as applied to use. Fig.,2 is a side view of the same. Fig; 3 isa cross-section on line x a: of Fig. 2. v .i

Similar letters of reference indicat-ecorresponding parts.

The piece A, which r term the fisin, isv

made as a segment of a circle, To this piece A, midway of its ends, the bar a is attached rigidly by the piece a', and in the direction radial of the segment. `At the inner end of bar a a short standard, b, projects, the end of which4 is rounded 'out to lie against the side of a spoke,rand the standard b is rigidlypbraced by braces b that pass from it inopposite directions to the outer ends of the sill A. Upon the upper side of A is a curved rest,c,formed with or attached to the sillA, for receivingy the spoke, the rest c being placed so that the spoke resting in it and against standard b will extend in the direction of bar a, and be parallel, or nearlyyso, therewith. f Y

The bar a, between sill A and standard b, carries a screw-rod, d, having an eye at one end for the spoke to pass through, and fitted at the other [end withy a nut, d', so that the spoke may be clamped tightly upon the standard b and rest c. j j

The above-described parts constitute the head or frame adapted for application upon the end of a spoke in the manner as indicated and as shown inthe drawings. n

The two spokes adjoining the one to which jects from the outer end of bar a.

the device is attached will rest against sill A,

land serve to prevent the'spoke twisting by I the action of the cutters.`

The crank-shaft e for carrying the auger or cutter is supported by the arm f, that proj The end of j'passing through bar a is formed with la screwthread, and fitted with set-nuts f at `each side of bar a, so that the arm may be set in and out as required, and clamped rigidly.

The arm f is braced against lateral movenient by divergent rods g g, extending to the sill A, upon opposite sides of the center, and the crank-shaft e, which bears the hollow cutter-head, passes loosely through an aperture in the end of arm f, which latter acts as a guide to hold the crank-shaft in proper position While cutting the tenon. As lthe cutter-head in this kind of a machine is hollow, or made to encompass the end ot' the spoke, it will be seen that no sti or -xed bearing in arm f is required, but only an ap.- erture'to hold the crank-shaft in the proper .axial line of rotation, the'spoke itself being relied on to center the tenon.

As the spokes of a Wheel are inserted with a dish which varies with different wheels, itis necessary to form the tenon at varying angles to the axial line of the spokein vorder to make the felly and tire set squarely on the dished spokes. For this purpose it is .necessary to alter the' axis of rotation of crank-shaft e. The' brace-rods g V are consequently made slightly elastic, and the arm f is made longitudinally adjustable byhaving its end which.

passes through bara threaded and clamped in its adjustment by nuts f f' upon opposite sides of the bar a. This permits the crankshaft to be adjusted j into' the position shown in dotted lines, which, it will be seen, allows the tenon to be cut at an angle to correct the dish ofthe wheel.V y Y i A The frame of the machine will preferably be made of wood to render it light.

It will be seen that the machine issimple and durable, and may beoperated with great facility and convenience.'V

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-.

IOC

l. The improved spoke-tenoning machine, 'l

consisting of the sill-piece A, having a rest, c, and adapted to overlap the adjacent spokes, as described, the bar a, standard b, clampingcutter-head shaft, the said arm being rigidly 1o connected with brace-rods g g, and made longitudinall y adjustable, substantially as and for TARRENCE CONNOR.
